Always ready

Your financial operations should not end at our UI. The CashFish API lets you push events in, subscribe to what happens inside, automate without code through the Zapier-compatible endpoint, and give AI agents safe read-only access through MCP with OAuth 2.1.

Why it matters

A financial platform that cannot talk to the rest of your systems just becomes the seventh disconnected tool. Closed data means manual exports, brittle copy-paste workflows and automations that break in silence.

What you get

  • Inbound and outbound webhooks for event-driven workflows

  • API keys for authenticated programmatic access

  • Zapier-compatible endpoint for no-code automation

  • Read-only MCP server built for AI agents

  • OAuth 2.1 authorization for agent access

  • Automations built on approved data — the same source of truth as your dashboard

How it works

1. Generate an API key and register your webhooks — a few minutes, fully documented.

2. Wire events in and out: trigger automations from CashFish activity, or feed external events into your workflows through the Zapier-compatible endpoint.

3. Point AI agents at the read-only MCP server with OAuth 2.1 — they read your approved numbers, and the approval gate keeps humans in charge of what counts.
